Gate Valve vs Check Valve – What’s the Difference

Gate Valves vs Check Valves

If you’re in the market for a valve, two of the most popular options you’ll come across are gate valves and check valves. While both are used to control flow in pipes or tubes, there are some major differences between them that make one a better choice than the other depending on your needs. This blog post will help explain how each type works and when it is best to use either one.

Gate Valve

A gate valve is a type of valve that uses an internal gate or wedge-shaped disc to stop and start the flow of liquid or gas through a pipe. The gate can be opened manually by turning the handle, or mechanically by using compressed air pressure. The gate is designed so that when it is open, it creates minimal obstruction in the flow path, allowing for maximum efficiency.

Check Valve

A check valve is a type of valve that prevents backflow in pipes or tubes. It works by using one-way flaps to allow fluid to pass through but not back up, which helps maintain proper water pressure and keeps contaminants from entering pipelines. Check valves come in various sizes and shapes, including swing, lift, globe, piston, diaphragm, ball, butterfly and plunger types. Each type operates differently depending on its design but all provide reliable protection against backflow.

Difference Between Gate Valve and Check Valve

The main difference between a gate valve and check valve is that a gate valve controls flow while a check valve prevents it from going backwards. A gate can be opened manually or mechanically while a check relies solely on gravity or pressure differences to open and close its flaps. Additionally, because check valves don’t have any moving parts they require less maintenance than gates do over time. Both types are important components of many plumbing systems as they help regulate water pressure and protect against contamination entering pipelines.

  • Gate valves and check valves are two types of valves that are used for different purposes.
  • Gate valves are used to control the flow of liquids or gases, while check valves are used to prevent backflow.
  • Gate valves are operated by a handle that is turned to open or close the valve, while check valves are automatically opened and closed by the pressure of the fluid.
  • Gate valves can be used in both high-pressure and low-pressure applications, while check valves are only suitable for low-pressure applications.
  • Gate valves are available in a variety of materials, including brass, bronze, cast iron, and stainless steel, while check valves are typically made from plastic or metal.


Both gate valves and check valves play an important role in regulating water pressure in plumbing systems as well as preventing contamination from entering pipelines. While there are some similarities between them—like how both use flaps—they operate differently with gates controlling flow while checks prevent backflow. Knowing which type of valve you need for your project will help ensure that you get the best results possible so make sure to do your research before making any decisions!
